hello
i have a question regarding a case where i need to associate an entity type (Bar) inside an embedded type (Foo).
is there any way to do that? it seems that i can't work it out as i constantly get a java.util.ConcurrentModificationException. i use Hibernate 3.5.3 configured with Spring 3 sessionFactory, and it's done quite simply:
Code:
@Entity
public class Bar {
...
}
@Embeddable
public class Foo {
private Bar bar;
@ManyToOne
@JoinColumn("BAR_ID")
public B getB() {
return this.b;
}
public void setB(B b) {
this.b = b;
}
}
now, whenever i try to run this, while loading (before committing any other actions), i keep getting:

if i omit the @ManyToOne annotation everything else is working and the application loads fine.
i don't understand what's wrong with having a @ManyToOne association inside an embedded type? after all, it will be a part of an entity at runtime..
thanks
